Where Does it Grow?

Non-Native

Starhorn is native to Asia. It is commonly used as an aquarium plant.

Is it Invasive?

Starhorn is considered a noxious pest because it grows so rapidly, out competing and eliminating native species.

This plant is not native to North America, but has naturalized in much of the United States. While it is not illegal to possess this plant in Texas, it should not be introduced into new water bodies and should be treated with herbicide when present.
